Interesting.

Part of this is, I'm sure, that the drive measurement is a meta-level away from the socket dimension, and has simply become so universal that no one questioned it. (Sort of like SAE measurements, before metrification became trendy, talking about meta-levels.) Another part of it is that, being square drive, there's a bit more room for play in the connection than in a hexagonal drive, and if it doesn't fit right you can usually take a grinder to it to make it work.

I just found it interesting.

Comment stupid observation... (Score 5, Interesting) 909

I had to equip my shop, and among other things picked up a set of socket wrenches, in both SAE and metric sizes. One thing I noticed, though, was that the socket drives were all in English measurements (1/4", 3/8", 1/2", 3/4") and that there were no metric-drive sets around anywhere. Just curious, are there any metric drive standards in Europe, and why haven't they found their way to the US? I'd expect at least some metric size sets from China to sneak in...

Data Storage

The Lies Disks and Their Drivers Tell 192

davecb writes "Pity the poor filesystem designer: they just want to know when their data is safe, but the disks and drivers try so hard to make I/O 'easy' that it ends up being stupidly hard. Marshall Kirk McKusick writes about the difficulties in making the systems work nicely together: 'In the real world, many of the drives targeted to the desktop market do not implement the NCQ specification. To ensure reliability, the system must either disable the write cache on the disk or issue a cache-flush request after every metadata update, log update (for journaling file systems), or fsync system call. Both of these techniques lead to noticeable performance degradation, so they are often disabled, putting file systems at risk if the power fails. Systems for which both speed and reliability are important should not use ATA disks. Rather, they should use drives that implement Fibre Channel, SCSI, or SATA with support for NCQ.'"

Comment Kmart special (Score 4, Interesting) 347

I wanted a standing desk for a cheap PC in my workshop, for looking up parts and reference, etc. I wound up going to Kmart, purchasing a cheap narrow PC desk with a roll-out keyboard rest, and a TV stand, and screwed one on top of the other. The result worked out well, with plenty of storage below the PC, and can roll around well.

Comment gaming keyboard (Score 1) 147

It'll take you longer than six weeks to get used to a chording keyboard or one of the alternative keyboards out there; typing one-handed may be annoying, but still more efficient. As to brackets and other special characters, I'd recommend getting a gaming keyboard with extra macro keys, and program those chars into them.

Comment far side (Score 3, Insightful) 120

Put the lasers on the far side of the moon. That way, they could never target Earth. You'd only be able to hit the asteroid for fourteen days out of every twenty-eight, but hey, it's safer, right?

(Actually, put two installations on its equator, both near but not within visible range of Earth, and you'd be able to hit it 90+% of the time.)

Comment Seconded (Score 1) 339

Unless you plan everything perfectly, at some point you're going to need a keyboard; and carrying a keyboard eliminates all the advantages of having a smaller PC. Use an ultraslim laptop or netbook.

Alternatively, make someone at the presentation site provide a PC or laptop, and carry all the data and an installer for the display prog on a USB key.
